A novel topology, Current-Fed MultiResonant DC-DC Converter (CF-MRC) was studied theoretically and experimentally. The main features of the proposed converter are an inherent protection against a short circuit at the output, a high voltage gain and zero voltage switching over a iarge range of output voitage. These characteristics make it a viable choice for the implementation of a high voltage ...

Abstract : This paper proposed a new high-voltage gain resonant switched-capacitor dc-dc converter for high-power offshore wind energy systems. The proposed new dc-dc converter is characterized by the resonant switching transitions to achieve minimal switching losses and maximum system effi ciency. Here, the converter operates at fi fteen times as high as the input voltage with a small device c...

This paper presents the functions of Series-Loaded Resonant Converter (SLRC). Series Loaded Resonant DC-DC converter is a type of soft-switching topology widely known for providing improved efficiency. Zero voltage switching (ZVS) buck converter is more preferable over hard switched buck converter for low power, high frequency DC-DC conversion applications. Zero Voltage switching techniques wil...

This paper presents an improved resonant parametric perturbation method for controlling chaos. The control target can be any periodic orbit. Anti-control of chaos or chaotization is also possible using this method. Application of the method is illustrated for a common current-programmed dc/dc converter which can easily become chaotic for a wide parameter range. Keywords— Chaos control, resonant...

The proposed zero-current switching switched-capacitor (ZCS SC) DC-DC converter is an innovative bi-directional power flow control conversion scheme. A zero-current switching switched-capacitor stepup/step-down bi-directional converter is presented that can improve the current stress problem during bi-directional power flow control processing. It can provide a high voltage conversion ratio of n...

Problem statement: A half-bridge LLC resonant converter with a voltage doubler rectifier has a simple structure and its Zero-Voltage-Switching (ZVS) capability is excellent from zero to full load condition. But conduction loss is more due to high circulating energy thus reducing the system efficiency. Moreover a variable frequency control method makes the control circuits more complicated than ...

In this paper a high frequency DC-DC converter fed by fuel cell is analyzed. The converter consists of full bridge inverter connected to full bridge rectifier through two planar transformers and parallel resonant. The mathematical model of the fuel cell is first presented and the average model of the converter is elaborated. The developed model is used to study the characteristics and dynamics ...
